FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent N0. 274,338, dated March20, 1883.

Applicationflled October 1,1862. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM FLETCHER JOLLEY, of Middlesex, in the countyof Yates and State of New York, have invented a new and ImprovedFire-Escape, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a fire-escape that is light,portable, and so arranged as to be folded into a small compass, to becarried on the ladder-trucks with the ordinary fire apparatus, to beused where it is desired, and to be placed below a person in denger in abuilding, and into which the person may jump without being injured.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

. which similar letters of reference indicate corterial. The edges ofthe canvas are turned over to form a hem, through which the rope B isrun, and it is also stitched together, forming pockets at to contain thecoil-spring sup ports 0.

1 Bars D, made of strong wood, and of suitable length, are' provided ateach end with loops d, that are connected to each other by rings F, thatpass through the loops d.

The coil-sprin g support 0 is formed ola rod, f, doubled upon itself,and having at one end a loop, 9, to receive the ring F. The rope B isalso secured in the loop g, and rests upon a movable washer, it, placedon the doubled rod f, and a washer, 'i, is firmly secured to theopposite end of the rod by passing the ends of the rod through thewasher and bending them outward or in any mannerto retain the springs.Between the washers h t is placed an open coilspring, j. One of thespring-supports U is secured to each of the rings F, and one or more tostaples e of the bars D, as may be requiredfor the supportoftheblanketA. When more than one of the spring-supports C are used theyare to be at equal distances apart upon the bar D, and are secured inthe poohets a in the blanket A. The rope B is passed through the loops 9and hem of the blanket A, and the ends firmly secured to each other. Abody falling on the blanket will cause the coil-springsj to yield,allowing the blanket to settle gradually.

The supporting-frame of the escape consists of four bars, G, of nearlyequal length, placed one on each side of a square block, H, that is atrifle larger in cross-section than the bars G, and to which they arepivoted by bolts k, the bars on the opposite sides of the block beingpivoted by the same bolt. One of the bolts 1c is placed a little abovethe other to allow them to pass in the block H. With this constructionthebars G are adapted to be placed in position for use, (shown in Fig.1,) and also to be folded parallel with each other. The upper ends ofthe bars Gare reduced and rounded to receive the rings F, which rest ontheshouldersformed byreducing theends of the bars. 7 The lower ends ofthe bars G are square, and on the outer side of each bar are placedextension-pieces I, that are of the same width as the bars G. Theextension-pieces I are adjustably secured ,to the bars G by clips J,that are attached to the lower ends of the bars G, and to the upper endsof the extension-pieces I, adapting the bars and extension-pieces tomove on each other toraise or lower the escape, or to adapt it to unevenground. The bars G and extension-pieces I are secured to each other whenproperly adjusted by the setsorews K, or in any suitable manner, toprevent the extension-pie'ce I from sliding upon the main bar G.

On the outer side of one of the bars D are two loops, l, to which isattached the upper end of a rope ladder, L, thelower end of whichreaches the ground, and by means of which a person may descend from theescape to the ground.

It will be seen that the supporting-frame and the blanket and its framemay be folded into asmall space, making the escape portable, and tooccupy but little space onaladder-truck.

The escape is easily set up, and when aperson jumps upon the blanketfrom a building the coil-springs are compressed, causing the force ofthe rapid descent to be broken gradually, preventing injury to theperson.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In blanket fire-escapes, the combination of the rigid bars I), havingend loops, cl (1, and the rings F, connecting said loops, to form astretching-frame for the blanket, adapted to be used as described.

2. A fire-escape blanket made with the radial pockets a, a rope pocketor receptacle about its periphery, and peripheral excisions shown inFig. 3 of the drawings,'and for the purpose specified. I

5. The combination, with rings F, connecting with loops onthe ends ofbars D, of the cross pivoted legs or bars Gr, held in said rings attheir upper ends, whereby a convenient detachable connection is formedbetween the stretcher-frame and the leg-bars, as shown and described.

6. In a fire-escape, the bars D and rings F, in combination with theblanketA and springsupports 0, substantially as shown and described.

7. The combination,with a fire-escape made substantially as shown anddescribed, of the ladder L, as specified.

8. In a fire-escape made substantially as shown and described, thesupporting-bars- G, block H, and extension-piece I, in combination withthe blanket A, spring devices 0, bars 1), and rings F, as set forth.
